A Maulana says that it is Sunnah to perform Nafl Salaat in a vehicle when outside the city limits.

Answer

Nafl Salaat may be performed in a vehicle outside the city limits. This applies to only the passengers.

The idea that the driver of a vehicle, i.e. a car, truck and the like, may also perform Salaat whilst driving, is absolutely corrupt. The writer justifies this with reference to Alamghiri and Shaami, but in the days of Alamghir and Shaami there did not exist motor vehicles.

To compare the driver of a motor car of our era to the camel driver or horse driver to which the Fuqaha refer is absolutely fallacious. How is it possible for a motor vehicle driver to perform Salaat whilst driving in heavy traffic or at speed on the highway? In a second of distraction he can cause a major accident. His life and the lives of the passengers are in grave danger.

Also, the motor car driver engages in amal-e-katheer perpetually. The writer lacks the ability to apply his mind constructively.
